LOCK-HINGE.'

SPECIFICATION forming part of Letters Patent No. 263,950, dated September 5, 1882.

' Application filed January 27, 1882. (No model.)

Ohio, have invented certain new and useful.

Improvements in Shutter-Hinges and I do hereby declare that the following is a full, clear, and exact description thereof, reference bein' g had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure l is a perspective view of my invention applied to a shutter. Fig. 2 is a perspec, tive view of the upper hinge. Fig. 3 is a perspective View of the lower hinge.

This invention relates to window-shutter hinges; and the nature of my invention consists in providing the eye of the lower hinge with a gravitati n g fin ger-catch, in combination with a recess of peculiar shape formed at the base of the pintle of the leaf, which is secured to the window-frame, whereby the shutter will be automatically locked when fully opened.

The following description will enable others skilled in the art to understand my invention.

A designates part of a shutter, and B a window-frame, which is hung thereto by my improved hinges.

G designates the lower hinge, and D the upper hinge. The upper hinge, D, is composed of a leaf, a, which is secured to the shutter,

and which is constructed with a vertical groove or recess, 1), extended into the eye, which passes through the hub c to receive the pintle. The

leaf a, which is secured to the window-frame,

shutter, and is constructed with ah ub, Gr, rising centrally from which is a pintle, J which terminates in a short extension, f, of smaller diameter than the pintle proper, which leaves a the pintle of the upper hinge is adjusted to drop into its eye. Then by slipping the hub of the lower swingingleaf from the shoulder the shutter will drop intoits place properly hinged.

he hub Gr is constructed with a recess, 70, in it, the outer shoulder, i,'of which is vertical, and the inner edge, j, of which is inclined from thetop of the hub to the bottom of this recess, as shown in Fig. 3. The leaf g of the lower hinge is secured to the window-frame, and it has an enlarged hub, G, through which is the eye to receive the-pintle of the leaf 9. This hub G has a passage through it of a dovetail or other suitable shape, in which passage gravitates freely a key, P, having a finger-piece on its lower end and a riveted or enlarged head on its upper end to prevent it from dropping out of it s place. A recess, a, is maderin the external surface of the hub G, to allow the key to be raised until its lower end is flush with the bottom of said hub. Now, when the key is raised out of its recess in hub G the shutter can be closed. In the actof opening the shutter the said key will, byits own weight, gradually move down the inclinedplane 9', so that when the shutter is fully opened the key will rest on the bottom of the recess and form a lock to keep the shutter open. The recess for the locking-key to play in may open into the eye of the hub G, or it may be separate from this eye.

The inclined plane j on the part G of the or recesses in them to receive the keys, and therefore I do not claim such devices when broadly considered.

Having thus fully described my invention, 5 what I claim as new, and desire to seeure'by Letters Patent, isv 4 In a Window-shutter hinge, the combination of the gravitating key P, the hub G, the hub G, having a recess to receive said key, an inclined plane, and a shoulder, i, substantially 10 as described.

In testimony that Ielaim the foregoing as my own I affix my signaturein presence of two subscribing witnesses.

I WILLIAM G. PEGKHAM.
